research Carbon, nitrogen, and sulfur elemental and isotopic variations in mouse hair and bone collagen during short-term graded calorie restriction
Calorie restriction changes the elemental and isotopic makeup of mouse hair and bone.
research ELECTRON MICROSCOPE STUDIES OF HAIR AND WOOL
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Alopecia Mucinosa
Alopecia mucinosa is a challenging condition with unclear diagnosis and treatment.
research Formation and Structure of Human Hair
Human hair growth and structure are influenced by keratin proteins, genes, melanin, and lipids.
research Trichothiodystrophy
Trichothiodystrophy is a condition with brittle hair and various physical and mental issues due to low sulfur in proteins.
research Structural and Molecular Hair Abnormalities in Trichothiodystrophy
TTD hair brittleness is caused by multiple structural abnormalities.
research Conformational differences in protein disulfide linkages between normal hair and hair from subjects with trichothiodystrophy: A quantitative analysis by Raman microspectroscopy
TTD hair is brittle due to fewer sulfur amino acids and unstable disulfide bonds.
research Differential diagnosis of hair loss in children. Differentialdiagnose des Haarausfalls bei Kindern
The document concludes that early diagnosis and treatment are crucial for children with hair loss to prevent permanent damage, although not all conditions can be effectively treated.
research A New Case of Isolated Trichothiodystrophy
A rare case of isolated trichothiodystrophy was identified, marked by brittle hair with low sulfur content.
research [Trichothiodystrophy: a morphological and biochemical study].
Trichothiodystrophy involves brittle hair due to low sulfur amino acids, not a transport defect.
research In utero Diagnosis of Trichothiodystrophy by Endoscopically-Guided Fetal Eyebrow Biopsy
Prenatal diagnosis of trichothiodystrophy is possible in the second trimester using fetal eyebrow biopsy, with sulfur content analysis being more reliable.
research Metal doped keratin film standard for LA-ICP-MS determination of lead in hair samples
A new method accurately measures lead levels in hair to assess exposure.
research Evolution of Trichocyte Keratins
Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.
research Nutrition of women with hair loss problem during the period of menopause
Eating a balanced diet with specific nutrients is important for menopausal women to manage hair loss.
research Further Insights in Trichothiodistrophy: A Clinical, Microscopic, and Ultrastructural Study of 20 Cases and Literature Review
TTD symptoms vary widely, requiring thorough evaluations.
research Copper and calcium uptake in colored hair
Hair coloring increases copper and calcium uptake, damaging hair and reducing shine.
research Giant Axonal Degeneration: Scanning Electron Microscopic and Biochemical Study of Scalp Hair
The patient's hair had unique damage and a lower sulfur-to-nitrogen ratio compared to relatives, but not compared to healthy controls.
research A RARE FORM OF SUPPURATING AND CICATRIZING DISEASE OF THE SCALP
A rare scalp disease causes hair loss, pus-filled nodules, and scarring.
research Recent advances in X-ray microanalysis in dermatology.
Trace elements like calcium, iron, and zinc are unevenly distributed in hair, while sulfur is even, and increased phosphorus and potassium levels are linked to skin reactions.
research A New Case of Trichothiodystrophy Associated with Autism, Seizures, and Mental Retardation
A rare case of trichothiodystrophy was found with autism, seizures, and mental retardation.
research Characterization of tiger tail banding and hair shaft abnormalities in trichothiodystrophy
Tiger tail banding and hair abnormalities are reliable indicators for diagnosing trichothiodystrophy.
research Utilization of L-Cystine and L- and D-Methionine by Mink during the Period of Intensive Hair Growth
Mink use L-methionine and L-cystine slightly better than natural amino acids for hair growth, but D-methionine is not effective.
research Trichothiodystrophy: Current Concepts
TTD patients don't have a higher skin cancer risk because their main issue is with transcription, not DNA repair.
research Silicon in hair loss: a preliminary SEM microanalysis study
The study suggests silicon might be important for healthy hair, as less silicon was found in people with hair loss.
research Molecular Signaling and Nutritional Regulation in the Context of Poultry Feather Growth and Regeneration
Good feather growth in poultry needs the right balance of proteins, amino acids, minerals, and vitamins.
research Age- and sex-dependence of five major elements in the development of human scalp hair
Calcium and magnesium in hair increase with age and are higher in adult women.
research Hair microscopy: an easy adjunct to diagnosis of systemic diseases in children
Hair microscopy is a simple and cost-effective method to help diagnose systemic diseases in children.
research Hair follicle dystrophy in a litter of domestic cats resembling lanceolate hair mutant mice
A litter of cats had a hair condition similar to a mouse mutation, leading to hair loss and abnormal hair and skin.
research Elemental content of anagen hairs in a normal Caucasian population studies with proton induced X-ray emission (PIXE).
PIXE is an effective method to analyze hair's elemental composition.
